Spinal Metastases of Supratentorial Glioblastoma with Primitive Neuronal Component.

BACKGROUND

Glioblastoma multiforme with a primitive neuronal component is a rare entity, with few cases reported in the literature.

CASE DESCRIPTION: A patient who had a supratentorial glioblastoma multiforme with a primitive neuronal component developed spinal metastasis during the disease course. With his history of leukemia during childhood, he was likely exposed to therapeutic ionizing brain radiation, which could have increased the risk of developing brain cancer in adulthood.

CONCLUSIONS

The range of incidence rates of dissemination in the literature is 2%-4%, typically in cases of cerebellar glioblastoma multiforme, but as high as 25% in autopsy series. Our case highlights several other topics in the literature, such as immunohistochemical patterns that differ between the primary tumor and spinal metastases and dissemination locations, typically leptomeningeal or ventricular invasion.
